Provided is a feature which allows an electric power steering device to improve the steering feel. The electric power steering device includes: a basic control amount calculating section configured to calculate a basic control amount corresponding to steering by a driver; a frictional force calculating section configured to calculate, by using a friction model, a frictional force corresponding to a wheel angle-related value, which is a value relating to a wheel angle of a steering device, and calculate a friction-originated control amount, which originates from the calculated frictional force; and a control amount calculating section configured to calculate a steering control amount in accordance with the basic control amount and the friction-originated control amount.
